  • The lower and upper flash points of the flammable binary system, butylacetate+2-propanol were measured by air blowing tester. The shape of the concentration-temperature region of flash depended on the components of the mixture in solution. The experimental data were compared with the values calculated by the reduced model under an ideal solution assumption and the flash point-prediction models based on Van Laar equation. Good qualitative agreement was obtained with these models. The prediction results of these models can thus be applied to incorporate inherently safer design for chemical process, such as the determination of the safe storage conditions for flammable solutions.

  • 인화점은 가연성 액체의 화재 위험성을 나타내는 지표로써, 가연성액체의 액면 가까이서 인화할 때 필요한 증기를 발산하는 액체의 최저온도로 정의한다. 인화점에는 하부인화점과 상부인화점으로 나누고 있으며, 일반적으로 하부인화점을 인화점이라 한다.(중략)

  • Due to the rising cost of energy, new separation processes based on extraction are becoming more attractive than before. Thus, the need for calculating and predicting liquid-liquid equilibria(LLE) compositions has very much increased. The purpose of this study is to determine the binodal curves, tie line, plait point, distribution and selectivity for the ternary systems of 2-propanol-water with methyl ethyl ketone, methyl isobutyl ketone, ethylacetate, toluene and o-xylene as solvents at $25^{\circ}C$. And those tie line data were used to examine thermodynamic consistency. The experimental tie line data were correlated with NRTL and UNIQUAC models.
